ansrmnnr; EASY. CHAIR.

Application filed? February To all whom it may GO'HGEW'H Be it known that I, STEVEN LIPTAK, a citizen of the United States, residing at Punxsutawney, in, the; county of Jefferson 5 and State of Pennsylvania, have invented certain new and useful Improvementsin ResilientEasy Chairs, of which the following is a specification.

This invention relates generally to chairs, having more particular reference toa chair having resilient legs, whereby it is constituted into an easy chair the invention having for an object the provision of a novel and simple arrangement of parts for this purpose, a further specific object relating to the means for producing a rocking chair effect.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the follow ing description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a perspective view of my improved chair.

Fig. 2 is a Vertical sectional view of one of the front legs.

Fig. 3 is a like view of one of the rear legs.

In Fig. 1 of the drawing the reference numeral 10 indicates the seat of the chair and 11 the back, these parts being of any suitable or well known construction. My improved resilient mounting means for the chair seat comprises a number of telescopic legs of which the front legs comprise the upper tubular elements 12 and the lower solid elements 13 and the rear legs comprise the upper tubular elements 14: and the lower solid elements 15, the elements 13 and 15 projecting slidably at their upper ends into the upper elements 12 and 1 1 as will be understood. Located in these upper elements 12 and 14 above the respective lower elements 13 and 15 are expansion springs 17 and 18 which form cushions between the said upper and lower elements, and thereby provide resilient legs for the chair. The lower leg elements 13 and 15 may be retained against ejection from the upper elements by means of the pins 20 thereon engaging in vertical slots 21 in the upper leg elements.

As here shown the front leg elements 12 are rigidly fixed at their upper ends to the underside of the chair seat 10, while each 13, 1924. Serial No. 692,458.

of the rear leg elements is formed on its upper end with an apertured ear 25' where by it is hinged, by apinion 26to-a hearing bracket 27 fixed to the underside ofithe chair seat. Real-ward swinging movement of the rear leg past vertical 'iosition is pre vented by means of a screw 23 threaded through a downwardly projected flange 29- onthe bracket 27 whilemovement in an op positedirection is yieldingly resisted bymeans of a spring 30 fixed at one endto the bracket-27 and bearing on the leg element 14.

In order to cause the chair to be more readily adjusted to swing on the rear legs after the manner of a rocking chair I preferably arrange means whereby the pressure of the springs 17 on the front leg elements 13 may be increased. As here shown the upper portion of the bore of each leg element 12 is screw threaded and has screwed therein a plug 33 against which the upper end of the spring 17 bears. This plug 33 is formed with an axial passage through which extends a turning bolt 34: which has a feather connection as at 35 with the plug and which projects at its upper end through the seat 10 and is formed with an enlarged flat head 36 sunk in a recess in the said seat, this head being here shown as formed with a pair of sockets 37 to receive a turning tool for the bolt. It will be apparent that by turning the bolt 34, the plug 33 can be moved vertically in the leg element 12 and thereby vary the pressure of the spring 17 on the lower leg element 13.

As will be apparent from the foregoing description, I have provided a novel form of resilient mounting for a chair which converts it into an easy chair adapted to operate after the manner of rocking chair.

While I have illustrated and described a preferred embodiment of my invention it is to be understood that I do not limit myself to the precise construction herein shown, and that various changes and modifications might be made therein without departing from the spirit and scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new and desire to protect by Let ters Patent of the United States is as follows:

1. A chair comprising a seat and legs, the rear legs being composed of upper and lower elements telescoping into one another means hinging the rear legs to the chair seat, and resilient means resisting swinging movement of said rear legs with respect to said seat.

2. A. chair comprising seat and legs, the legs being each composed of upper and lower elements telescoping into one another, and a spring interposed between the upper and. lower elements of each leg, means hinging the rear legs to the chair seat, a solid abutment member holding said rear legs against swinging movement in one direction, and a spring engaging each rear leg to resist swinging movement in an opposite direction. 3. A chair comprising seat and legs, the legs being each composed of upper and lower elements telescoping into one another, and a spring interposed between the upper and lower elements of each leg, means hinging the rear legs to the chair seat, a solid abutment member holding aid rear legs against swinging movement in one direction,

and a spring engaging each rear leg to re sist swinging movement in an opposite direction, said solid abutment being adjustable.

4-. A chair comprising a seat and legs, the legs being each composed of upper and lower elements telescoping into one another, a cushioning spring interposed between the upper and lower elements of each leg, brackets fixed to the chair seat and having the upper ends of the rear legs hinged thereto, screws threaded through said brackets and forming abutments holding said rear legs against swinging movement in one direction, and springs bearing on the said rear legs and resisting swinging movement of the legs in an opposite direction.

In testimony whereof I have aflixcd my signature.
